    Particle physics (ref)

    group theory is an integral part of particle physics and one needs a good understanding of this before one switches on to reading particle phy ......please give me a good reference for this ... i m new to both group theory and particle physics ...thosugh i 've read about the historical...

    Concept of field

    can ne 1 explain 2 me the canonical formalism of generalising the concept of field in QFT...i m not 2 sure abt the replacement of generalised coordinates q(i) i=1,2,...... n with phi(x)

    Potentials in relativity

    please elaborate ......" particle quantum mechanics is valid in the nonrelativistic regime by definition refuses to obey relativity ...this is not bcoz we write non relativistic hamiltonians bt the concept of potentials is untenable in relativity ...since it assumes the transfer of...

    Why t3 , t8 plane ?

    in sampling about the flavor u,d,s ...we use the t3, t8 generators amd plot all the possible combinations of their eigen values ....and then define u ,d , s.... i want 2 ask that why specifically these 2 SU(3) generators are used t o define flavors? I have vague answers 2 this question but...

    Mass dimensions

    what do we mean by mass dimensions ..? and if we r talking abt the general dimensions here then y s the term mass included here? what is the mass dimension of the fields?(field here means the set of numbers at each point in space time )
